Hi, i just bought 3 quarts of Mobil 1 Synthetic Gear Lubricant 75W - 90.
I decided eh i better do a quick search before i swap the fluid. So after searching around i am all mixed up in what i should do. The bottle says it is used where GL-5 is reccomended. I asked the guy at Pep Boys and he told me that oh its above GL-4 so it will be fine if not better and Mobil 1 is good quality + it was 4$ more each than the sold out synchromesh. I have read that people say that the GL-5 will eat up the synchros and that Mobil 1 is not good. I was going to buy the pennzoil synchromesh but they were all out of it. Is it not good to use, is it worth it to go return it and buy the synchromesh? Please anyone help before i put this in my car.
